MEIIALLIC STRUCTURE, SUCH AS DOORS AND THE LIKE.

Tu cZZ whom it may concern:

lie it knownthat l, lTlARULl) l lAlllSll, a

. citizen of the United States of America, and

residing in the-borough of Brooklyn, in the county ofliings and State ofNew York, have invented a certain new and Improved Metallic Structure,Such as Doors and the like, of which the following is a spcciticzv tion.

My invention relates to metallic structures such as doors, partitions,frames and windows and the object thereof is to produce a metallicstructure of improved artistic appearance which can be economicallymanufactured and which shall be light and at the same time strong.

Further objects of my invention will be hereinafter referred to in thefollowing detailed description of the invention. V

In the accompanying drawings, the invention is illustratedina metallicdoor, but it is to be understood that, except as specifically pointedout, the invention is susceptible of modification without departing fromthe spirit of my invention and it is equally applicable to structuresother than doors.

Figure 1 is an=elevation of a door embodyingmy invention; Fig. 2 is abroken section thereofion'the line .22, Fig. 1 drawn to a largerscale;and Figs. 3 to 8 are sections'of modified details.

The structure illustrated is a door of the type in which the framemembers, via, the

stiles 10 and 11 and cross rails 12, 13 and it neled construction.

of-each face oft-he door, are integral and the door frame is completedby suitably securing together these two opposite faces B at the edges ofthe door. Where panels 15 and .16 are employed as illustrated, these areindependent from the frame members and are held in position upon-theframe lly suitable securing means. The structure is thus distinctfrom-the type of the 'door i1 which Specification of Letters Patent. IPgmtentgd 348; Egg} 1% Application filed May 20, 1912. Serial No.698,503.

curing together the two door faces maybe varied in many ways, I preferto effect-this, for the top rail and stiles, by bending'over at rightangles and for an equal distance from each facetheir respective margins17, the edges of which are recurved to form open channels 18. Thebottoms of the latter, in assembled condition, are thus 'jmxtaposed on aline midway between the two door faces. T 0 unite these edges and at thesame time to stiffen and strengthen thedoor, I provide a stiffening bar19 extendingas a strut member between the inner faces of the two sheetsA and B and having its edges recurved to engage and interlock with thechannels 18. The parts may now be elecw trically welded or-rivetedtogether, preferably the former, as giving the more finishedappearance.it will be observed that inthiscondition the edges of the door areclosedon three sides, while the bottom edge is left open for the purposeof perfecting-the hint at theedge of the lower panel as will behereinafter explained.

Presuming that the upper panel 15 to be inserted in the registeringapertures of the door is to be a pane of glass, the

edges of the plates A and B at theglass aperture are cut on the miter atthe corners and the edges are folded inward to form an open channel 21and then recurved to form a second and parallel channel 22 oppositelyfaced. A molding 23 with glass supporting ledge 24 spans the spacebetween faces A and B, and its edges are insci-ted in the oppositechannels 22. ening bar is also spaced between the plates A and B withthe side flanges of tlie barinserted in the opposite channels 21. Afterthe glass 15 is in position, a retaining molding '26, one edge ofwhiclrentcrs the channel 22, is pressed against thc face.of the glassand is drawn into snug engagement therewith by screws 27 which enterthreaded holes in the reinforcing bar 28 welded or otherwise secured toone face of the supporting ledge 24.

The advantage of the construction shown is obvious, since it permitsthereadyremoval of the molding 26 for the insertion of a panel of glass.If thispanel ismade of non-o breakable material so that replacement isa0 1 A stitfnot likely to be necessary, the construction employed forthe lower panel is preferred. At the lower panel opening the edges ofthe apertures are fdlded on three sides to a panel supporting nmldingtion only, to form the single. channel 31.-

For a one piece panel 16, as shown in Fig. 2,

33 with panel receivingslideway 34. is spanned between the channels 30on'three sides. At the bottom of the panel the construction must bedifferent in order to permit the insertion of the panel which is slidthrough the bottom of the door into the depression 34: of the side andtop molding 33. A following and supporting molding 35 engages the loweredge of the panel and is in turn held in position by the stiffening bar36, the channels 37 of which receive the edges of the molding andtheinner edges of the opposite channels 31. The parts are securedtogether in any suitable way, preferably by welding.

Thebottom of the door, which has been left open for the insertiontherethrough of the panel 16, moldin 35 and stiffening bar 36, is closedby an lnverted stiffening bar 38, the edges of'which are turned down andwelded in the channels 89 formed by the upturned edges 40 of the bottommargins of the side plates A and B. A recess ll is thus afforded for thereception of weather stripping or other material which it may be desiredto arrange at the bottom of the door.

Themanner of constructing and assembling the door is readily understoodand may be varied in many ways. .For example," the blank of sheet metalis first formed with the central apertures for the panels, and themargins of the panel apertures and of the sheet as a whole then foldedto form the edges of the door and the inturned keyways or channels. Atthe corners of the door the metal is unavoidably cut away slightly toafford clearance for the folding d1es, and sufiicient room is thusafforded at the top of'the verticaledges for the passage of the fiatreinforcing key bar 19 through the clearance space at the corner intoengagement with the" channels 18. This corner seam is in any eventunavoidable, by reason of the fact that the margins of the sheetsarefolded oyer, both at the top and at the sides of the ,door, and theinsertion of the key 19 aids in filling the seam which is closed by aline of solder, or electrical welding in accordance with the processdisclosed in my Patent 1,034,290. The keys 19 for the vertical edges ofthe door are then passed into enga ement with the channels formedthereon, t e'keys being insertedfrom the bottom of the door, at whichpoint the clearance for the folding dies is formed. The. faces of thedoor are now united, with the panel apertures in register. The uppermoststifl- Lose-934. I

ening spacer bar 25 is now placed in position by passing it up sidewisebetween the recurred marginal edgcs 21 at the panel aperture. and thendrawing it down into the position shown. Any suitable means may beemployed for this purpose, 5]., a wire welded at one end to the barandcut off after the latter has been drawn down into position. The bar 25is then secured by welding the joint between the same and the bottoms ofthe channels 21. The molding 23 is then placed in position, the panel1?) inserted and the retaining moldin 26 screwed into position. Thesecond spacing bar 25 is then passed up from the aperture for panel 1630 and welded in position, thus completing the upper portion of thedoor. The lower portion is inlarge part a repetition of the upper part,and no difficulty will befound in understanding its assembly from thepreceding description. p

A door thus constructed presents the great advantage over adoorassembled from independent stiles andrail members that the weldingof all joints betwee v the parts may be accomplished from the interiorof the door, thus presenting an exterior free from the blemishes orblisters which in eritably accompany a welded joint. Further y .it'presents great advantages over a door 5 with depressed panels in that itpermitsof a variety of design and artisticity of mold ing which arewholly beyond the range of practicability for doors of the pressed paneltype.

Obviously the particular moldings and closures may be varied in manyways. Thus in Fig. 8 l have shown the bottom edges of the faces A andB'carried down perfectly straight and the opening closed by the inser- 5tion of a flanged stiffening bar 4:2 which is welded in position. InFig. 4 I have shown a modified form for the edges of the top cross railand stiles. The edges of the latter are folded to form paralleloppositely o faced channels 43 and 44, in one pair of which engagethe-edges of a flanged stiffening bar 45 and in the other pair an 0pp0--sitely faced stiffening bar-46. ln Fig. 5' the panel is supporteddirectly by the stiffening bar 47 and-moldings 48 are arranged on eachside of the panel to give a'finish' to the joint. In Fig. 6 the panelsupporting molding 49 is provided with upturned edges 50 which engage inthe channels 31 at the lower edge of the panel aperture, together withthe flanges of the stiffening bar 51. The latter in turn may bereinforced by asecond stiffenin bar 52' oppositely faced.

and sides of the panel, be engaged in the channels 30, while the bottomedge engages in the channels 37 of the stifiening bar 36.

()r as in Fig, 8, the lower edge of the panel may be recu'rved to engagein the channel 31 with the flanges of the stiffening bar 51.

panel supporting means have been assembled I in position.

A metallic structure of the character described comprising front andback face sheets having rail and stile portions and having registeringperforations to receive an inserted panel section, the margin of saidpanel perforation being folded and recurved on certain sides to formparallel ,oppositely faced channels, and one margin of said panelaperture being folded in only one direction, for the purpose described.

3. A metallic structure of the character described comprising front andback face sheets having rail and stile portions and having registeringperforations to receive an inserted panel section, the margin of saidpanel perforation being folded and recurved on certain sides to formparallel oppositely faced channels, and one margin of said panelaperture vbeing folded in only one direction, together with panelmolding engaging in the channels facing the channel aperture, andstiffening bars engaging in the oppositely as described.

4. A metallic structure of the type described, having front, and backface sheets, each comprising rail and stile portions, the top facedchannels, substantially and side margins of the sheets being folded atright angles and their edges recurved inwardly to form open channels,the bottoms of which unite to form an edge closure for the structure,stiffening bars engaging. the opposed faces of the door and having theiredges angled into locking engagement with said marginal channels of thefront and back face sheets, in combination With means insert-ible at theremaining edge of the structure after the other edges are closed,spacing said edges apart but forming an edge closure, all the edges ofsaid structure being continuous and free from aper tures, fill pieces orthe like, substantially describe I I In testimony whereof I have signedmy name-to this specification, in the presence of two subscribingWitnesses. 4
